Definitions

  • the invention discloses a caisson breakwater which is able to protect a port or a marine sheet of water with a small wave reflection, and is able to convert wave energy into electric power. 5
  • Each caisson is subdivided into a number of cells by vertical walls. Typically the caissons are manufactured in dry docks, towed and sunk. The cells are filled with sand and/or gravel and/or concrete or other kind of ballast. Then a superstructure is cast in concrete.
  • US patent 6,450,732 Bl has disclosed a submerged caisson on the seabed, with an air pocket and a vertical duct having the same width as the caisson.
  • the upper opening of the vertical duct is beneath the sea level, and through this opening, the water alternately enters the caisson and exits from the caisson.
  • the height of the air 25 pocket inside the caisson is tuned with means for pumping or releasing air. Tuning is made so that the eigenpenod of free oscillations inside the caisson be close to the wave period.
  • An embodiment of patent US 6,450,732 Bl comprises a self- rectifying turbine (e.g. a Wells turbine) that is a turbine whose direction of rotation does not change if the flow is reversed.
  • a self- rectifying turbine e.g. a Wells turbine
  • This turbine is in a small section of the vertical duct and is driven by the high-speed water- flow in said duct.
  • the plant disclosed by US Patent 6,450,732 Bl is an excellent absorber of wave energy, and it can be used very well to build submerged breakwaters with a very low environmental impact. These breakwaters are able to protect beaches from 5 erosion, but they cannot protect a port because a part of the wave energy goes beyond these breakwaters.
  • the caisson of US Patent 6,450,732 Bl having an air pocket in pressure, needs a compressor, and needs control against air leakage.

  • OWCs oscillating water columns
  • OWCs Conventional wave energy converters known as OWCs (oscillating water columns) are widely described in the scientific literature. They may be coastline OWCs (see U.S. patent 5191225), breakwater OWCs (see Takahashi S. et al., Proc. 23 rd Int. Conf. On Coastal Eng., 3440-3453, A er. Soc. Civil Engineers, New York, 1992),
  • OWCs 15 or floating OWCs (see U.S. patent 6194791), according to whether they are installed on a coast, or in a caisson breakwater, or in a sinking structure.
  • OWCs essentially, consist of a box which rests on the seabed, with the roof above the sea level and with a large vertical opening in the main vertical wall (the one beaten by waves). This vertical opening extends from nearly the seabed to nearly the sea
  • an OWC is not a Uconduit with an air pocket acting as a spring.
  • an OWC cannot exploit a natural resonance where the eigenperiod of free oscillations in a U-conduit is equal to the wave period. This is why for improving the efficiency, some OWCs exploit a forced resonance with some complex devices for phase control in each individual wave (see Korde U.A. Applied Ocean Res. 13,
  • OWCs call for a large vertical opening in the main vertical wall so that their structure differs deeply from the compact structure of conventional caisson breakwaters. Moreover, to improve the efficiency, OWCs need some complex devices for phase control.
  • the objectives of the present invention are to make a caisson breakwater which: (i) is suitable to protect a port;
  • (ii) reflects only a small share of the incident wave energy, and converts wave energy into electric power; (iii) has turbines above the sea level, does not need means such as compressors, and does not need control against air leakage; (iv) has an absorption device consisting of a Uconduit with an air pocket acting as a spring; (v) does not need complex devices for phase control, given that it exploits a natural resonance where the eigenperiod of oscillations in the U- conduit is close to the wave period; (vi) has the same compact structure and well-established building trade as conventional caisson breakwaters.
  • a caisson 1 comprises: (i) a vertical duct 2 which extends substantially along the whole caisson 1 and is connected with the sea through an upper opening 6; (ii) a room 3 which extends substantially along the whole caisson and is connected with the vertical duct 2 through an opening 7; the base of said room 3 being beneath the sea level, and the roof 8 of said room 3 being above the sea level; (iii) an air-duct 4 connecting the room 3 with the atmosphere; (iv) a seff-rectifying turbine 5 in the air-duct.
  • the vertical duct 2 and the room 3 form a Uconduit wherein the air in the room 3 acts as a spring.
  • the eigenperiod of oscillations in this U-conduit grows as: (i) the width of the vertical duct 2 is reduced, (ii) the length of the vertical duct 2 is increased, (iii) the width and height of the room 3 is increased, (iv) the diameter of the air-duct 4 is increased.
  • the width and the length of the vertical duct 2, and the width and the height of the room 3 are fixed so that the eigenperiod be close to the wave period of the waves which convey the largest amount of energy in the course of a year.
  • the plant of the present invention works as follows. Under wave action, pressure fluctuates on the outer opening 6 of the vertical duct 2. These pressure fluctuations cause oscillations of the water in the U-conduit which consists of the vertical duct 2 and the room 3. As a consequence the air in the room 3 is compressed and expands, and an alternate air flow is produced in air-duct 4. This air flow drives the self- rectifying turbine 5. Thus, waves do not propagate into the plant of the present invention, while, as said, waves propagate into OWCs.
  • valve 9 must be closed.
  • the water level in the room 3 may be measured by means of an ultrasonic probe attached to the roof 8. Given that the plant exploits a natural resonance there is no need at all for phase control. Finally, given that the average air pressure in the room 3 is equal to the atmospheric pressure, there is no need for control against air leakage, nor there is need for compressors. Given that the plant exploits a natural resonance in a U-conduit, it needs only a relatively small hoiizontal-outer-opening 6.
  • the U-conduit (that is the vertical duct 2 and the room 3) can be well above the base of the caisson 1, so that we can fill the room beneath the U-conduit with concrete. That is why the caisson breakwater of the present invention has nearly the same compact structure as a conventional caisson breakwater.

  • a second advantage is that a more regular production can be obtained. Indeed, even when there is no wind, the factory can produce electric power, exploiting the energy of swells.
  • the caisson breakwater of the present invention has the same solid structure in reinforced concrete as a conventional caisson breakwater. Also the building trade is the same, and the overall size is nearly the same - typically, the width of a caisson breakwater of the present invention proves to be about 5% greater than the width of a conventional caisson breakwater, under the same safety factors against sliding and overturning, and under the same load on the foundation.
  • the hydraulic apparatus is particularly simple - typically, it consists of a single turbine per caisson, with a diameter between lm and 1.5m. Control is reduced to a minimum, given that the plant exploits a natural resonance in a U-conduit and does not call for phase control.
  • the breakwater of the present invention has two important advantages over a conventional caisson breakwater. First, it converts part of the incident wave energy into electric power. Second, it reflects less wave energy. Our computations, based on numerical simulations of random wind- generated waves with some characteristic spectra, show that the breakwater of the present invention is able to absorb more than the 70% of the incident wave energy per year, and is able to convert into electric power more than one third of the absorbed energy. For this estimate use has been made of the plots of Curran and Gato (Proc. Last. Mech. Engrs. 211,1977) for the efficiency of a simple monoplane Wells turbine.

Abstract

La présente invention concerne une maçonnerie de brise-lames pourvu d'une conduite verticale (2), d'une chambre (3), d'une conduite d'air (4) et d'une turbine autorectifiante (5). Sous les fluctuations de pression de vague appliquée sur l'ouverture extérieure (6) l'eau entre et sort en alternance, de sorte que l'air présent dans la chambre (3), soit comprimé et dilaté en alternance, et qu'un flux alterné d'air s'écoule dans la conduite d'air (4). La conduite verticale (2) et la chambre (3) forment une conduite en U et l'air présent dans la chambre (3) agit comme un ressort. La période caractéristique des oscillations dans cette conduite en U croît à mesure que la largeur de la conduite verticale (2) se rétrécit et/ou que la longueur de cette conduite verticale augmente, et/ou que la largeur et la hauteur de la chambre (3) augmente. Cette période caractéristique est fixée proche de la période de vague des vagues porteuses des plus grandes quantités d'énergie dans une année, de manière à absorber une très grande quantité d'énergie de vague.
